Ritesh P. Shah has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Physical vapor deposition targets
    Patent number: 6713391
    Abstract: The invention includes a non-magnetic physical vapor deposition target. The target has at least 30 atom percent total of one or more of Co, Ni, Ta, Ti, Pt, Mo and W, and at least 10 atom percent silicon. The target also has one phase and not more than 1% of any additional phases other than said one phase. In another aspect, the invention includes a non-magnetic physical vapor deposition target consisting essentially of Co and/or Ni, silicon, and one phase.
    Type: Grant

  • Ni-plated target diffusion bonded to a backing plate and method of making same
    Patent number: 6555250
    Abstract: The invention includes a method of forming a heat treated sputtering target assembly. A backing plate is diffusion bonded to a sputtering target to produce a sputtering target assembly. The sputtering target assembly is heat treated to precipitation harden the backing plate of the assembly. The heat treatment includes heating and quenching, with the quenching being performed by immersing the backing plate in a quenchant without submerging the sputtering target.
